Engine painting and a whine-reccomendations

[Fazer99]

Only ever used high temp paint on exhausts.. ps I painted the silver lines on the engine fins. Leaving raw alloy was where the problem of flaking black paint on the fins starts.. imo

Only if you use rough grade paper rather than smoothing it down with much finer grade paper. Every now and then I give my engine a coating of WD40 or something similar (after the bike has been washed I should add) and that seems to help keep crap getting under the paint and causing it to flake, it seems to work a bit like lacquering.
